Technical description
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view all Kirki frontend forms and read stored visitor form submission data, including contact details, messages, and any other visitor-provided information submitted through site forms.
